Their work is definitely of high quality.
I am so glad that I have been able to find out about these guys through a referral. The installation they did is amazing. Their work is definitely of high quality and they are professionals at what they do.
I'd say thank you to Las Vegas Air. It's almost a month now that our heating not working and we've tried different companies but Las Vegas Air is the one who stands out- affordable, professional and polite over the phone. After calling for schedule service, they came on time and diagnose the problem. I thought it needs to be replaced, but they did their best to fix it- prompt, very knowledgeable and clean service. Kudos!
Good, professional job on outside electrical boxes and new furnace upstairs. Checked ducts. Very thorough job.
Very professional company as well as very affordable. Great bunch of guys. I called them and they showed up within a hour. And I received a phone call when they were on the way. Very Professional and courteous. They fixed my Air Conditioning at a reasonable price. I recommend them to all.
